General Information
Overview
EN 4192:2001 - Aerospace series - Pipe coupling 8°30' in titanium alloy - Tees, reduced bulkhead branch is a CEN/AECMA standard that defines the characteristics, configuration and acceptance requirements for reduced tees used as bulkhead branches in aerospace fluid systems. It applies to titanium-alloy tees for 8°30' pipe couplings rated to a nominal pressure up to 28 000 kPa and a temperature range of 55 °C to 135 °C.
Key topics and requirements
- Geometry and dimensions: Tee configuration, dimensional limits and connection interfaces are specified in figures and tables (connections 1, 2 and 3; horizontal/vertical drill depths). Connection 1 shall be ≤ connection 2.
- Threading: MJ threads and limit dimensions referenced to ISO 5855-3 for fittings used in aerospace fluid systems.
- Materials: Titanium alloy per the referenced AECMA/EN material specifications (EN 3311, EN 3312, EN 3314, EN 3315).
- Surface treatment & lubrication: Threads and sealing faces must be abrasive-blasted using non‑metallic grit and lubricated per EN 2491; lubricant film thickness 0.005–0.013 mm.
- Internal finishing: Internal radii R = 0.3–1.0 mm and internal surface roughness 0.8 µm; hand deburring is not permitted.
- Marking & identification: Marking requirements follow EN 2424 (style A) and include code/identity blocks.
- Mass & installation data: Mass values and installation dimensions are provided (tables and figures) to support weight budgeting and bulkhead installation details.
- Acceptance & technical specs: Qualification and acceptance follow EN 3275 (type II) and related verification provisions.
